Patients will be from 10 different European countries and care settings (primary and secondary care and different specialties). A one-year patient recruitment period per country is planned, but it could be longer if patient recruitment numbers are not reached. Patient data will be documented at baseline (BL), one annual data documentation point during the four-year follow up (FU), and at final assessment. Patients who permanently discontinue edoxaban during the observation period will continue to be followed annually for a further two years, or until the end of the observational period (whichever comes first).
